Abstract
The present invention discloses the construction method of a kind of basement bottom plate rear pouring tape waterproof construction, belongs to building waterproofing technique field.This construction method step is as follows: bury drain header and branch drain in drainage trap underground to base plate catch pit, is then paved with graded broken stone in drainage trap and forms rubble drainage layer, then arranges mortar block and mounting base reinforcing bar in both sides, bottom, post-cast strip；Mortar block is installed in both sides, top, post-cast strip after post-cast strip side form is installed；Carrying out post-cast strip concreting after pouring both sides, post-cast strip underplate concrete, take curing concrete under the conditions of band film heat and moisture preserving, curing time is no less than 14 days.The inventive method can reduce basement bottom board water pressure, it is achieved basement bottom plate rear pouring tape water-proof function, makes concrete pouring quality be guaranteed.
Description
Technical field
The invention belongs to building waterproofing technique field, be specifically related to a kind of basement bottom plate rear pouring tape waterproof construction
Construction method.
Background technology
In big basement structure construction, need to set post-cast strip to solve differential settlement and to reduce shrinkage stress
Problem, the structure design of post-cast strip and construction technology can affect after the construction quality of whole basement structure,
Even affect normal usage function.It is main that present stage basement bottom plate rear pouring tape waterproof construction mainly uses to block up
Construction method, the construction measure of waterproof layer is set at the bottom of pre-embedded steel slab waterstop and plate in the soleplate, but underground
Room bottom plate rear pouring tape yet suffers from leakage scenarios in various degree.
Summary of the invention
The technology present in existing basement bottom plate rear pouring tape construction method that present invention aims to is asked
Topic, it is provided that the construction method of a kind of basement bottom plate rear pouring tape waterproof construction.
The construction method concrete steps of a kind of basement bottom plate rear pouring tape waterproof construction provided by the present invention are such as
Under:
(1), after blinding layer 6 has been constructed, in drainage trap, drain header 5 and branch drain 7 are buried underground
To base plate catch pit, it is paved with graded broken stone in drainage trap below post-cast strip 2 after installation and forms rubble
Drainage layer 4, then lays plastic sheeting sealing coat 9 on rubble drainage layer 4 along direction, post-cast strip 2.
(2), before base plate lower floor reinforcement installation, 2 liang, post-cast strip, side lower part arranges mortar block 8, by reinforcing bar
It is placed in the groove of described mortar block 8, after preventing in basement bottom board 1 casting process concrete to flow into
Water in band 2, then other baseplate reinforcing bar is installed.
(3) installing post-cast strip side form, post-cast strip side form 3 uses dense mesh and framework of steel reinforcement to install, close
Mesh steel wire is placed on the concrete side of basement bottom board 1, and firm with tied silk colligation；Framework of steel reinforcement and the end
Plate top bars and base plate lower floor reinforcement welding are fixed, and install sand at top bars mesh sheet post-cast strip upper position
Slurry block 8.
(4) pour both sides, post-cast strip underplate concrete, pour post-cast strip by underplate concrete job specfication requirement
Both sides concrete vibration compacting, clear up the loose concrete in both sides, post-cast strip in time and rinse well.
(5) treat that basement bottom board concrete shrinkage and building settlement are basicly stable and reach design and want seeking time
After carry out post-cast strip concreting, pour before cleaning post-cast strip 2 in foreign material and dismounting be positioned at post-cast strip
The mortar block of 2 upper positions, carries out reinforcing bar checking adjustment, waters water-wet, uses admixture micro-expanding agent
Concreting post-cast strip, abundant vibration compacting, take curing concrete under the conditions of band film heat and moisture preserving,
Curing time is no less than 14 days.
The present invention has a techniques below feature:
1, late poured band structure is simple, it is simple to constructing operation and quality control；
2, basement bottom board water pressure is reduced, it is achieved basement bottom plate rear pouring tape water-proof function；
3, without hydrops in post-cast strip, concrete pouring quality is guaranteed；
4, employing rubble drainage layer replacement post-cast strip bottom reinforcement bars concrete reinforcement structure, cancellation coil waterproof layer,
Steel plate water stopper, has saved cost, accelerating construction progress.
Accompanying drawing explanation
Fig. 1 is the post-cast strip waterproof construction schematic diagram after the inventive method construction.
In figure: 1: basement bottom board；2: post-cast strip；3: post-cast strip side form；4: rubble drainage layer；5:
Drain header；6: blinding layer；7: branch drain；8: mortar block；9: plastic sheeting sealing coat.
Detailed description of the invention
The construction procedure of basement bottom plate rear pouring tape waterproof construction provided by the present invention is specific as follows:
1, after blinding layer 6 has been constructed, in drainage trap, drain header 5 and branch drain 7 are buried underground
To base plate catch pit, drain header 5 first half is provided with the osculum of φ 8-10mm, in underground after installation
Bottom plate rear pouring tape bottom, room is paved with graded broken stone and forms rubble drainage floor 4, and macadam gradating is preferably 10-31.5；?
After on rubble drainage layer, spread a slice width 1.5m thickness 0.5mm plastic sheeting sealing coat 9 along direction, post-cast strip 2 sky.
2, before base plate steel bar binding, mortar block 8 is placed at post-cast strip, both sides lower position, by bottom layer of the reinforcing steel
Mesh sheet lower floor reinforcing bar is placed in the groove of mortar block 8, prevents coagulation in basement bottom board 1 casting process
Soil flows in post-cast strip 2, then installs other baseplate reinforcing bars.
3, post-cast strip side form 3 uses dense mesh and framework of steel reinforcement to install, and dense mesh is placed on underground
Room base plate 1 concrete side, and firm with tied silk colligation, framework of steel reinforcement and base plate top bars and base plate lower floor
Reinforcement welding is fixed, and installs mortar block 8 at top bars mesh sheet post-cast strip upper position.
4, both sides, post-cast strip 2 basement bottom board 1 coagulation is poured by underplate concrete arrangement and method for construction and code requirement
Soil vibration compacting, clear up the loose concrete in both sides, post-cast strip 2 in time and rinse well.
5, treat that basement bottom board 1 concrete shrinkage and building settlement are basicly stable, and reach design when requiring
Post-cast strip 2 concreting can be carried out after between；Foreign material in cleaning post-cast strip 2 and dismounting position before pouring
In the mortar block 8 on top, post-cast strip 2, flushing moistening of watering, and carry out reinforcing bar checking adjustment；Use
The concreting post-cast strip 2 of admixture micro-expanding agent, abundant vibration compacting；Take band film heat and moisture preserving condition
Lower curing concrete, curing time is no less than 14 days.
